    I built a tool (https://1mil.app/hn) to help me test my intuition about various weird business ideas that were on my mind. Initially, I wanted to create a database with 1 million business ideas (hence the name - "1 million opportunities"). But turned out to be a dumb idea already. So instead I built this tool that returns only 10 ideas. It's all based on your input, market + your background. The first release scored on demand only and it gave false confidence. So I rebuilt the the scoring around "winnability": can a solo founder with a specific background "win" against what…

    Hey HN, I’m Kyrylo. I recently created a small tool that lets you gather, refine, and validate SaaS/startup ideas using AI. I used to jot down my product ideas in a note apps, but it wasn’t very practical for collecting feedback or refining them. So, I built this tool to make the process easier. Here’s how it works: 1. Enter a brief description of your idea. 2. The app uses AI to generate project details. 3. Share your idea via a link that includes a feedback form. It’s pretty straightforward, and I’d love to hear your thoughts or any suggestions!

    I was working on validating some of my own project ideas. While trying to find how to validate my idea, I realized the process itself could be turned into a tool. A few late nights later, I had something that takes any startup idea, fetches discussions, summarizes sentiment, and gives a quick “validation score.” It’s very rough, but it works, and it’s already making me rethink a few of my own ideas. It's still a work in progress. I don't actually know what I'm doing, but I know it's worth it. Honest feedback welcomed! Live demo here: https://validationly.com/

    Hello HN, Later today I'll be shutting down the servers and moving on. This is my 5th startup and the 4th failure. The reason is very simple: I understimated the cost of user acquisition. This is the second time this happened. The dozens of users actually love the software and are using it on a daily basis. I'm ruthless when it comes to coding and money. So, if you are building a startup: do not ignore how much money you will have to spend to get a user. If you are not able to find that number, something could be wrong with your model. Maybe someone smarter than me could write something…
